Vanguard Mining Receives Final Environmental Licenses for Yuty Prometeo Uranium Project

Vancouver, BC — February 6, 2026 — Leads & Copy — Vanguard Mining Corp. has received its final set of Environmental Licenses from Paraguay’s Ministerio del Ambiente y Desarrollo Sostenible (MADES), bringing the total to four.

The licenses are part of the regulatory advancement of the Company’s 90,000-hectare Yuty Prometeo–San Jose Uranium Project in southeastern Paraguay.

In conjunction with the licenses, Vanguard has applied for its Prospection Permit with Paraguay’s Vice Ministry of Mining and Energy (VMME), a step toward full-scale uranium exploration authorization across the project area.

The Environmental Licenses now encompass Vanguard’s entire land position at Yuty Prometeo–San Jose and represent the final environmental approvals required for the project. No additional environmental licenses are outstanding.

Vanguard says this positions the Company at an advanced stage of the Paraguayan permitting process.

This regulatory milestone comes as Paraguay’s role in global critical-mineral supply chains gains visibility. Paraguay recently participated alongside the United States at a high-level ministerial summit in Washington, D.C., hosted by the U.S. Department of State. The February 4 meeting focused on technical cooperation, strategic investment, and supply-chain alignment for critical minerals, including uranium, lithium, and rare earth elements.

Deputy Minister of Mines and Energy Mauricio Bejarano said surging global demand has firmly placed Paraguay on the radar of international partners.

Vanguard believes this alignment reinforces the strategic relevance of its uranium portfolio as the United States and its allies accelerate efforts to secure diversified, transparent, and geopolitically stable sources of nuclear fuel and other critical materials essential to energy security, advanced technologies, and national defense initiatives.

Chief Executive Officer of Vanguard Mining, David Greenway, said the receipt of the final MADES Environmental Licenses marks a significant permitting milestone and further advances the Yuty Prometeo–San Jose Uranium Project toward prospection authorization. He added that these approvals meaningfully de-risk the project and reflect continued regulatory progress in Paraguay.

As global demand for uranium and other critical minerals continues to grow, Paraguay is emerging as a stable and underexplored jurisdiction of increasing strategic relevance, Greenway said. Vanguard is focused on responsibly advancing high-quality uranium assets and positioning the Company to participate in the development of diversified and secure nuclear fuel supply chains.

Vanguard’s four concessions, including the three San Jose and one Yuty Uno concession, span approximately 90,000 hectares (222,395 acres) within the Paraná Basin. The project area is located adjacent to Uranium Energy Corp.’s (UEC) established Yuty Deposit, which hosts an Indicated resource of 8.96 million pounds of U₃O₈.

The Yuty Prometeo consists of four concessions—three San Jose concessions and one Prometeo concession—covering a combined area of approximately 90,000 hectares (222,395 acres) within the uranium-rich Paraná Basin in southeastern Paraguay.

The Prometeo Concession spans approximately 27,666 hectares (68,368 acres) and is directly contiguous to UEC’s Yuty Project. Historical records reference 27 drill holes on the Prometeo property, averaging 165 meters in depth. Spectral Gamma Downhole Logging of all these boreholes indicated the presence of uranium in seven of the holes -which averaged 175 m deep. Six of these seven holes reported anomalous uranium values of 0.01-0.02% U₃O₈, and the seventh hole reported strongly mineralized rock of 0.05% to 0.10% U₃O₈ throughout its 107-meter length.

Data from previous work by the Anschutz Corporation suggest that the Prometeo block lies along geologic trend with UEC’s contiguous Transandes block.

The San Jose Concessions encompass approximately 62,210 hectares (153,754 acres) across three adjacent claims situated along the Upper Permian–Carboniferous contact, approximately 100 km northwest of UEC’s Yuty Project and 40 km west of its Coronel Oviedo Project. A radiometric car survey conducted over a 40 km by 10 km area delineated significant uranium anomalies across the properties.

Collectively, these concessions represent a strategically positioned and highly prospective uranium exploration asset within one of South America’s uranium districts.

The drill results referenced in this release are historical in nature. Vanguard has not yet completed the work necessary to independently verify these results in accordance with NI 43-101 and therefore they should not be relied upon. The Company plans to complete confirmatory drilling to verify the historical information.

UEC’s adjacent Yuty ISR Project in southeastern Paraguay spans approximately 117,359 hectares (290,000 acres) and hosts an Indicated resource of 8.962 million lbs U₃O₈ (9,074,000 tons grading 0.049% U₃O₈), and an Inferred resource of 2.203 million lbs U₃O₈ (2,733,000 tons grading 0.040% U₃O₈), as disclosed in its July 1, 2022, technical report titled “Yuty Uranium Project Initial Assessment US SEC Subpart 1300 Regulation SK Report, Paraguay SA.”

UEC’s Yuty project is considered amenable to low-cost, lower-impact in-situ recovery (ISR) mining method extraction UEC employs at its Texas operations.

UEC secured a 100% undivided interest in the Yuty Project through its March 30, 2012, acquisition of CUE Resources Ltd.

Vanguard’s management cautions that past results or discoveries on properties in proximity to Vanguard may not necessarily be indicative of the presence of mineralization on the Company's properties.

The Republic of Paraguay is an emerging mining jurisdiction in the heart of South America, known for its political stability, low sovereign risk, and investor-friendly regulatory environment. The country has a democratic government, strong legal protections for foreign investment, and a growing interest in unlocking its untapped mineral potential, particularly in uranium, rare earth elements, and base metals. With abundant land, a relatively low population density, and improving infrastructure, Paraguay is increasingly recognized as a geopolitically stable and strategically attractive destination for mining companies seeking long-term growth opportunities.

Vanguard Mining Corp. is a Canadian mineral exploration company focused on the discovery and development of high-value strategic minerals. The Company is currently advancing uranium exploration projects in the United States and Paraguay, with a focus on identifying and developing assets critical to the global energy transition. Vanguard is committed to responsible exploration and value creation through the acquisition and advancement of highly prospective uranium properties.
